This invention relatesto telephone sets,

more particularly to improvements in desk' sets which particularlyadapt the phone to use` vithout requiring that the user hold the rcceiverelement as in thewell known types.`

lt is among the objects of this invention to provide a telephone set in which the receiver.

and transmitter' are permanently secured to the standard or supportin such manner that the receiver may be positioned for use at either the right or left hand side of the support.

Another object ofthe invention is the provision of ineans for automatically replacing the ringing circuit of the telephone after use and for placingthe telephone entirely within the controll ofthe switch board operator who can replace the telephone set in the normal condition for use if it is inadvertently left in thetalking position by the user.

apparent from a consideration of the accompanying drawings in which like reference characters designate like parts and in which F ig. 1. is a front elevational view of a telephone` set embodying the. principles ofthis invention; Fig. 2 is a side elevational view thereof; and Fig. 3 a diagram illustrating the electric connections and the manner of releasing the receiver element to close the telephone circuit by theenergzation of the. ringing circuit thereof.

As shown in Figures 1 and 2, a standard or support 1 of the customary construction is l' provided with a pivotal arm 2 which is pivoted at 3 to the top of the standard and adapted for swinging movement thereon. The arm 2 is provided with a transmitter 4. and a: receiver 5, the opening of the latter being angularly disposed with respect to the mouth piece 7 of the transmitter in the order i of or similar to the well known type of desk phones in which' the transmitter and receiver are a unitwhich is movably connected VVwith the desk set or support. y

Attached to the swinging arm 2 or foimed integrally'therewith, is a disk element 8 having indentations or notches 9 therein, the

notches or indentations being disposed 180or apart and are adapted to cooperate with a PATENT OZFFIC latch or plunger in the form of afspring pawl l 10 by means of which the `arm 2 -is heldin theliorizontal position with the receiver ele.-

' ment7 in either the left or right `hand position as may be -convenientto theuser. It is of course evident ,that a'largenumbcr of shallow notches may be employed and that the spring pawl l can be made `to operate as a` slip ratchet by simply moving` thearm: 2v against the pressure of the vspring,.thereby eliminating the thumb latch 13. .i

The receiving element '5 embodying the usual .magnet iron, will be, of considerably more weight than the :transmitter element 1, j and if the arm 2Vwere released `by the removal ofthe pawl 10,the arm with the transmitter vand-*receiver would. assuinethe dotted 'line position with :the receiver suspended downwardly and the transmitting element extend-l f ing at the Vtop ofthe base or supportlr i. These and other objects will. become more The pawl forms an .extension or. an integral portion of a rod 11 which isiconnected tothe movable armature 12 offa relay;A as shown in Fig. .fyand the armature12` is funther movable by a thumb latch 13 which prol jects at theside ofthe standard las shown in Fig. 1. The rod 11 `is further connected this corresponding to the receiver hookin the customarytype of telephone.

- ture 12 to which the rod 11 is secured, thereby disconnecting the speaking circuit and establishing the ringing circuit in the same manner as though the circuit :were made by placing the phone in upright position or depressing the latch 13.

In this manner the telephone operators have full control ofthe telephones and c'anreestablish the bell ringing circuitsif theyare inadvertently left open by the user or if by any meansthey should become open by accidental contact With the telephone.
